@MrDeathFox maybe

@monocolotion do you still need help

download steam but don't run it, it worked to me. :>

@Glumpf you're welcome 😊

You and your friend download Radmin VPN, create a network, and let them join it. If you are hosting the game in Radmin, there is an IP address. Copy it and send it to your friends. Go to a private match and start the map you want to play alone. When the game starts, your friend can connect by hitting the console command or the Grave key ~ and typing CONNECT then the IP you provided them.

Hey, yes, you can start it directly with the "launch" flag:
boiii.exe -launch
